Yeah, I was originally going to suggest only that an alternate timeline had gribblies from beyond time and space was attempting to conquer humanity, and they too were setting up sleeper agents, but I felt like that would just make it "Eldrich Things vs Robots".
Transhuman Spess Mahreen splat sounds good to me.
I think though the core thing is that you're all ostensibly working for the exact same goal here-that's why it's a metaphor for modern politics. All of you want the AI to thrive and become strong and wise and powerful. Whether that involves working with humans, exterminating humans, being built as a military project, evolving out of Facebook, or whatever-the details are what you disagree on, not the goal.
